New injector idle surge problem

922 2
Well I traced part of my check engine lights and misfires to a bad injector
It was reading zero ohms
After researching what injectors to buy I bought a brand new Bosch

Not able to test drive as we are getting a winter storm here in Michigan
But after letting warm up in the garage I’m getting a idle surge maybe 200 Rpms
And it’s idling at around 1000 rpm
Almost like I have a vacuum leak and forgot to put a hose on.

Any ideas here?

Where the injectors go into the intake manifold there are 2 types of grommets. 1 that is soft and 1 that is some type of hard rubber. How come I have 2 different types? Don't know, but anyway, had a huge vacuum leak from the base of the injectors. Installed the right grommets and now no more surging. Thanks

Sprayed carb cleaner around all the injectors with no change in rpm
Also around all vacuum lines I took off.
only thing I can thing of is maybe the cars ecu needs to relearn?
Expecially since who knows how long the injector has been bad
I can’t take if for a drive since we got some snow but it’s on my list
Also I plugged battery and that seemed to help at first but then it came back to surging.
